I think you're integrate!

[Ikerous]

How do you integrate x^x?
My first instinct is to re-write it as e^(x*lnx)
Albeit i have no clue where to go from there...

Thanks for any help you can provide ^_^

[Tr0n]

x + y = z

 

[Ikerous]

x + y = z

So basically... pi = 4!
Genius!

o.< Any clue how to actually help..?

You shouldn't be asking me a high school drop out...math is not my strong suit.I'm more of a history buff.

Hm.. if James Madison were x^x... how would you integrate him...?

Anyone from Alabama can tell you that Pi = 3.


Mmmmm, Alabama Pi.

Set him up on a date with Halle Berry.

Hell whats integrate?

Like I said I'm not good a math.I don't even know what x^x relates to or anything.

 

[Ikerous]

XD I'm gonna assume you're joking
Cuz somehow i doubt horizontal asymptotes would help any...
(Plus Madison would so end up going for J Lo)

 

[Laivasse]

isn't X^X one of those anime fanboy smileys?

 

[Ikerous]

Lol, i think thats X_X....
Hm.. ya think one of them might know?

 

[Hectic Glenn]

inter what?

 

[JDB]

Int x^x

yo yo yo

y = x^x ... oui

ln = x*ln(x) ... si

then it's an easy-peasy by parts integral

Peace.. JDB

 

[JDB]

nearly forgot

don't forget to take the antilog when you've got the integral!!!!!!


Laters.. JDB

 

[Hectic Glenn]

Hes registered just to tell you that Ikerous.....thats such a beautiful story ;( ;( ;(

Amen brother

 

[Ikerous]

Integration by parts? Sweeet.
Now i need to find a site that'll teach me that XD
Thanks a ton!!!

Wow. This was a test question for me two days ago. And guess who got it right?

Lol, wanna be freindly and show me the steps? ^_^
::Reading up on integration by parts::
-_- stoopid limited first semester calc knowledge

x(2)-42(7.123 / 6.21)=9.12-(32.1/ -12.14)

Hope this helps.

Umm take a lighter and burn the papers!!!!!!!!

I could help you next week, because next week is when we learn this shiite

Sucks for you.

 

[Ikerous]

Lol, okay, i've figure out how integration by parts works and i managed to integrate x*ln(x). Now what do i do with the other side being ln...?

 

[Kommie]

Sucks for you.

You meanie

/me runs away crying, stopping only to throw a rock at tron

 

[Dan]

I'm pretty sure that x^x can't be done with standard mathematical functions. Some functions are just non integratable. You could however approximate it with Reiman (sp?) sums or the antiderivative of a Taylor series polynomial

 

[kirovman]

I'm pretty sure every function is integratable, just some cannot be done analytically (ie the way you normally do it, by calculus analysis).

Some need to be done numerically (ie by computer).

 

[lePobz]

JDB is a maths-genius mate of mine, I asked him the question and he signed up to post his help on it... i'll get him back here next time he logs on.

Lol, okay, i've figure out how integration by parts works and i managed to integrate x*ln(x). Now what do i do with the other side being ln...?

make both sides e^[whatever], so
e^(ln) = e^(1/2*x^2*ln(x)-1/4x^2)
which turns into
y = e^(1/2*x^2*ln(x)-1/4x^2)
EDIT:
wait actually you'd have to integrate the ln first, since ln = x*ln(x), so you get
y*ln - y = 1/2*x^2*ln(x)-1/4x^2
so
y = -(1/2*x^2*ln(x)-1/4x^2) - y*ln

and mu ha ha, you have two variables and only one equation, and God takes no pity upon your pathetic soul and you get the problem wrong no matter what! MU HA HA HA HA!!! :rolling:
